Janome ยท .JEF
Embroidery files for the Janome MB-4S / MB-4Se (4 needles)
Turn any picture into a .JEF sized for the Janome MB-4S / MB-4Se (4 needles). Choose its hoop in the studio, match each colour to a real thread, watch every stitch sew out on screen, then copy the file to your machine.

How it works
- Add your picture Upload a JPG, PNG, WebP, BMP or GIF. Bold, flat colours and clear outlines stitch best, and a PNG with a transparent background leaves the background unstitched.
- Pick your machine and hoop Choose your machine and hoop and the design is sized to fit, with its stitch speed and format set.
- Match real threads Every colour is matched to a real spool from your thread brand, with its number. Change any of them.
- Preview and download Watch every stitch sew out on screen, then download the file and copy it to your machine.
Hoops
- M1: 240 x 200 mm (9.4 x 7.9 in)
- M2: 126 x 110 mm (5.0 x 4.3 in)
- M3: 50 x 50 mm (2.0 x 2.0 in)
Getting the file onto the machine
Copy the .JEF to a USB stick, plug it into the machine and open it from the embroidery mode's USB menu. Older models without a USB port use a card reader or Janome's transfer software; the manual shows how.
Tips
- Pick the hoop you'll actually sew with: the studio sizes the design to fit it, up to 240 x 200 mm.
- Each colour change moves to the next of the 4 needles, in the order of the thread list. Designs with more than 4 colours need rethreading partway, and the studio tells you when.

Questions
What file format does the Janome MB-4S / MB-4Se (4 needles) use?
.JEF. It also reads .DST, but .JEF is its own format.
Can I put a JPG straight onto the Janome MB-4S / MB-4Se (4 needles)?
No. Embroidery machines sew from stitch files, not pictures. InstaEmbroid turns the JPG into a .JEF with every stitch planned, which the machine can open.
How big can a design be?
Up to 240 x 200 mm (9.4 x 7.9 in) in the M1 hoop.
